For that investigation, which accords with faith, which builds, on the foundation of faith, the august knowledge of the truth, we know to be the best. Now we know that neither things which are clear are made subjects of investigation, such as if it is day, while it is day; nor things unknown, and never destined to become clear, as whether the stars are even or odd in number; nor things convertible; and those are so which can be said equally by those who take the opposite side, as if what is in the womb is a living creature or not. A fourth mode is, when, from either side of those, there is advanced an unanswerable and irrefragable argument. If, then, the ground of inquiry, according to all of these modes, is removed, faith is established. For we advance to them the unanswerable consideration, that it is God who speaks and comes to our help in writing, respecting each one of the points regarding which I investigate. Who, then, is so impious as to disbelieve God, and to demand proofs from God as from men? Again, some questions demand the evidence of the senses, as if one were to ask whether the fire be warm, or the snow white; and some admonition and rebuke, as the question if you ought to honour your parents. And there are those that deserve punishment, as to ask proofs of the existence of Providence. There being then a Providence, it were impious to think that the whole of prophecy and the economy in reference to a Saviour did not take place in accordance with Providence. And perchance one should not even attempt to demonstrate such points, the divine Providence being evident from the sight of all its skilful and wise works which are seen, some of which take place in order, and some appear in order. And He who communicated to us being and life, has communicated to us also reason, wishing us to live rationally and rightly. For the Word of the Father of the universe is not the uttered word (λόγος προφορικός), but the wisdom and most manifest kindness of God, and His power too, which is almighty and truly divine, and not incapable of being conceived by those who do not confess--the all-potent will. But since some are unbelieving, and some are disputatious, all do not attain to the perfection of the good. For neither is it possible to attain it without the exercise of free choice; nor does the whole depend on our own purpose; as, for example, what is destined to happen. “For by grace we are saved:” not, indeed, without good works; but we must, by being formed for what is good, acquire an inclination for it. And we must possess the healthy mind which is fixed on the pursuit of the good; in order to which we have the greatest need of divine grace, and of right teaching, and of holy susceptibility, and of the drawing of the Father to Him. For, bound in this earthly body, we apprehend the objects of sense by means of the body; but we grasp intellectual objects by means of the logical faculty itself. But if one expect to apprehend all things by
